AB It is shown that the process of mutation in the CYP2 family of the superfamily of P450 cytochromes is species-specific (man, rat, and mouse). It is also shown that, within one species (rat), different families (CYP2 and CYP11) have different mutation spectra, indicating a high specificity of the mutation process for the families of cytochrome genes. A similar specificity was demonstrated for five families (CYP1, CYP2, CYP6, CYP7, CYP11) as compared with globins and prions. The analysis of the evolutionary mutation pattern, and the pattern of pseudogenes and damaged alleles of the CYP21 family (found in patients with congenital adrenal hyperplasia) does not confirm the widely accepted hypothesis that mutations arising in pseudogenes are transduced to normal alleles of the CYP21 gene through gene conversion.
